<div id="classDescription">
CCheckBoxColumn represents a grid view column of checkboxes.
<br/><br/>
CCheckBoxColumn supports no checking (read-only), single check and multiple checking.
The mode is determined according to <a href="CCheckBoxColumn.html#selectableRows">selectableRows</a>. When in multiple checking mode, the header cell will display
an additional checkbox, clicking on which will check or uncheck all of the checkboxes in the data cells.
The header cell can be customized by <a href="CCheckBoxColumn.html#headerTemplate">headerTemplate</a>.
<br/><br/>
Additionally selecting a checkbox can select a grid view row (depending on <a href="CGridView.html#selectableRows">CGridView::selectableRows</a> value) if
<a href="CCheckBoxColumn.html#selectableRows">selectableRows</a> is null (default).
<br/><br/>
By default, the checkboxes rendered in data cells will have the values that are the same as
the key values of the data model. One may change this by setting either <a href="CCheckBoxColumn.html#name">name</a> or
<a href="CCheckBoxColumn.html#value">value</a>.</div>
